Our editorial take on the Apollo X4 Heritage Edition
The Universal Audio Apollo x4 Heritage Edition is a desktop Thunderbolt 3 audio interface positioned for project studios and mobile recording applications. It offers 12x18 I/O, including four mic preamps and two Hi-Z inputs, coupled with robust analog output specifications, including a 127 dBA dynamic range on both line and monitor outputs. The integration of QUAD Core UAD processing allows for real-time effects, supported by a substantial bundle of 34 UAD plug-ins included in the Heritage Edition.
Its desktop form factor and thoughtful features such as integrated talkback, switchable phantom power for individual inputs, and a built-in monitor controller with remote functions, mono, mute, dim, and alt monitor controls suggest a focus on a streamlined workflow. The digital I/O through TOSLINK Optical ADAT / S/PDIF provides expandability for recording and playback scenarios.
Considering its feature set and the inclusion of powerful DSP, the Apollo x4 Heritage Edition appears to be a comprehensive solution for creators requiring high-quality conversion and real-time processing within a compact design.
